3 way switch does not allow to switch off after firmware upgrade

After upgrading the firmware in my Multiplus Compact 12-1600-70 to firmware version 2606474, the external 3 way switch no longer allows me to turn off the multi. I can still control "charge" vs. "inverter" state, but in the "off" position of the external switch, the multi goes to "inverter" state.

What is wrong?

Original firmware of the multi is 2606154.
